As for deepest team ever, no.
I'm not even sure it's the deepest team of this decade.
2012-13 LakersDwight Howard, Pau Gasol, Metta World Peace, Kobe Bryant, Steve Nash, Earl Clark, Jordan Hill, Antawn Jamison, Jodie Meeks, Steve Blake
When your top five players averaged 28/5/4 (Kobe), 20/14.5/2/1.5/2 (Dwight), 17/10/3 (Gasol), 12/10/3 (Nash) and 17/6/2 (Jamison) in he season prior...then then you have a lot of talent.
Add to that a bunch of solid role players like Earl Clark, Jordan Hill, Jodie Meeks, Steve Black and MWP and you have one of the deepest and most talented teams ever assembled.
Unfortunately that all came crashing down when Nash and Dwight suffer from major injury issues, and when (even worst than that) the Lakers decided to hire Mike D'Antoni as head coach.
The end result for this team was a combination of bad luck, poor decision making, and poor chemistry and it will probably go down in the books as one of the most epic failures in NBA history...but nobody can deny the amount of talent/depth this team had. This year's Warriors don't even come close.
2012-13 Miami HeatLebron, Wade, Bosh, Ray Allen, Shane Battier, Mario Chalmers, Rashard Lewis, Chris Andersen, James Jones, Mike Miller
This team doesn't look that deep on paper, mainly because after LBW (Ray Allen at a BIG stretch) there was nobody else on this team even resembling a star a this point in their careers. Battier and Chalmers were basically 3-and-D guys, Andersen was career role player, and the others (Lewis, Jones, Miller and arguably even Ray Allen) had become one dimensional role players by this point in their careers.
But those guys still count as depth, because Miami's entire offensive game plan essentially involved surrounding Lebron and Wade with shooters in order to space the floor and give those guys the room they needed to operate...and Miami had arguably more deadly shooters than any other team in the league. Between Mario Chalmers, Ray Allen, Rashard Lewis, James Jones, Mike Miller, Shane Battier and Chris Bosh the Heat were able to ensure they always had 3-4 dangerous shooters on the perimeter, and that made it absolutely impossible for teams to risk double-teaming Lebron or Wade.
If you define depth as how deep you can go in your roster and still find starting calibre talent, then this team wasn't that deep. However if you define depth as how deep you can go in your roster and still find guys who help you win games, then that team was as deep as any.
2010-11 Orlando MagicDwight Howard, Rashard Lewis, Hedo Turkoglu, Ryan Anderson, Brandon Bass, Vince Carter, Gilbert Arenas, Marcin Gortat, Jameer Nelson, Mickael Pietrus, J.J. Reddick, Jason Richardson, Quentin Richardson, Jason Williams.
This team had 11 guys on the roster who played 20 or more minutes per game.
Nine of those 11 guys averaged double figure scoring - Dwight Howard (22.9), Jason Richardson (13.9), Hedo Turkoglu (11.4), Rashard Lewis (12.2), Jameer Nelson (13.1), Vince Carter (15.1), Brandon Bass (11.2), JJ Reddick (10.1) and Ryan Anderson (10.6).
The other two were Mickael Pietrus (6.7) and Gilbert Arenas (
who also contributed in their own ways.
Not a while lot of star power after Howard (Carter, Arenas, Richardson and Lewis were all once stars, but had long faded by this time) but that depth is just ridiculous.
2009-2010 CelticsPierce, Garnett, Ray Allen, Rajon Rondo, Tony Allen, Glen Davis, Eddie House, Kendrick Perkins, Nate Robinson, Rasheed Wallace, Shelden Williams, Marquis Daniels
At this point Tony Allen was starting to show his potential as an elite defensive specialist, Glen Davis was a legit 6th man candidate, Eddie House and Nate Robinson were our offensive spark plugs, Rasheed Wallace was an outstanding interior defender who could stretch the floor, and Shelden+Marquis were out effort/hustle guys.
When you have a solid bench like that and your fourth best player (Rondo) is averaging 14/9/5/2 then you have a pretty deep team.
2010-11 CelticsPierce, Garnett, Ray Allen, Rajon Rondo, Glen Davis, Jeff Green, Nenad Krstic, Jermaine Oneal, Kendrick Perkins, Shaquille Oneal, Nate Robinson, Delonte West, Marquis Daniels)
This team had the potential to be the deepest team in the Big 3 era. If all our guys were healthy then pre-trade our depth chart would have been:
R Rondo / N Robinson
R Allen / D West
P Pierce / M Daniels
K Garnett / G Davis / J Oneal
K Perkins / S Oneal
Then the trade happened, and our depth char would have been
R Rondo / D West
R Allen / M Daniels
P Pierce / J Green
K Garnett / G Davis / J Oneal
N Krstic / S Oneal
No matter how you look at it, that's some pretty crazy depth. Yes I know that Shaq and Jermaine we shells of their former selves at this time, but Jermaine was still an excellent rim protector (and decent rebounder) and even at 39 years old Shaq was still undefendable - we were dominating teams anytime he was on the court.
Unfortunately we lost Perk for the season, then lost Shaq for the season, lost Delonte for much of the season, lost Jermaine for most of the season, lost Marquis, then did the trade for Krstic...and lost him in the playoffs. So then by the time we finished out tour of the playoffs, our depth chart had become..
R Rondo / D West
R Allen / V Wafer
P Pierce / J Green
K Garnett / J Green
J Oneal / T Murphy
Ouch...
But in terms of the actual names on the roster, had we remained healthy, that would have been an incredibly deep team and IMO at least on par with this year's Warriors.
